Rainbow triangles in arc-colored digraphs

Wei Li, Shenggui Zhang, Ruonan Li

Let $D$ be an arc-colored digraph. The arc number $a (D)$ of $D$ is defined as the number of arcs of $D$ . The color number $c (D)$ of $D$ is defined as the number of colors assigned…

Rainbow triangles in arc-colored tournaments

Wei Li, Shenggui Zhang, Yandong Bai +1

Let $T_{n}$ be an arc-colored tournament of order $n$ . The maximum monochromatic indegree $Δ^{- m o n} (T_{n})$ (resp. outdegree $Δ^{+ m o n} (T_{n})$ ) of $T_{n}$ is the maximum number of…
